Thereafter migration continued with less force up to Jan., 1885, the date of the last schedule to hand.
Inchkeith.—This land-locked station returns a light schedule—of considerable interest, however, as carrying out what has been remarked by us in previous reports, that when birds do occur here on migration it is usually with S.W. and westerly winds, whether in spring or in autumn. The Siskin seems to frequent Inchkeith as a regular migrant, and Titmice are also regular in appearance.

Turdidæ.—In spring, migration at Sumburgh Head (April only, large flocks of Common Thrushes on 1st, wind light S.E., clear, along with Starlings and Linnets), and Pentland Skerries (indication in March, and partial and remittent in April, but no great rush evident). At Bell Rock (great rush recorded on 6th and 8th March of Thrushes, Ring Ouzels, light S.E. wind), and at I. of May, but rush not observable here on 6th and 8th, there being only two records of Blackbirds and a few Redwings, owing to local wind being light W. and haze. Earliest record at I. of May, Feb. 20th, one Redwing with Blackbirds and Thrushes; a rash, and latest records, also at I. of May, on 29th and 30th April, along with Robins, Redstarts, &c., with S.E., or light S.W., of Ring Ouzels. Light records in March; on 9th and 10th twenty Fieldfares—"a good number"—with light N.E., clear, and N.N.E. and rain.
In autumn the migration was pronounced, and whilst desultory movements continued during September and October, the heaviest rushes are recorded in the middle of November. Records of Dippers, one on Aug. 2nd and another (well described) on Aug. 29th, at I. of May; wind light W., clear. The place where they were observed was afterwards pointed out to me—viz., at the edge of a stagnant pool of water near the "Mill Door" on the I. of May. Earliest record of Fieldfare, Sept. 10th, at I. of May, light S., haze; latest of same species, on Dec. 31st, and Jan. 19th, 1885, also at I. of May; variable, haze. Earliest record of Common Thrush, also at I. of May, the day after, viz. Sept. 11th, light S., haze; and latest, at I. of May also, on Dec. 22nd, when "a few" were noticed. Earliest Missel Thrush on Sept. 27th (seen by J. A. H. B.), also at I. of May, with gale, W.S.W., and latest Oct. 14th; but others, no doubt, have escaped special records, and have been confused with other species. Earliest Redwings do not appear in the schedules till Oct. 2nd, also at I. of May (J. A. H. B.); on 7th a few more, followed by scattered records till Nov. 12th, when old and young struck in numbers at Bell Rock, and the rush of this and of Fieldfares took place on the 4th and 5th of November, continuing till the 17th, with Blackbirds, male and female, and intermittently until December. Earliest Blackbirds Sept. 11th,—"not many,"—at Isle of May.
Rush of Thrushes, Nov. 7th (light) at Pentland Skerries, and Nov. 30th, at I. of May (considerable). Rush of Fieldfares and Redwings (indicated) at N. Unst, on Nov. 5th, with a few Blackbirds,—all flying S.,—indicated at Pentland Skerries, 5th, 7th, to 12th, with Blackbirds and a few Thrushes and Woodcocks, on 12th. At Dunnet Head a few Blackbirds and Thrushes seen daily between Oct. 1st and Nov. 13th. Rush of Ring Ouzels ("great numbers") at Bell Rock; and rush of Fieldfares and Redwings at I. of May on 4th and 5th. At N. Ronaldshay also a rush visible on the 8th, with Woodcock, Crows and Rooks; Nov. 7th and 8th, wind E.S.E., a great rush. All during October the above-named Turdidæ appeared in small numbers, the wind prevailing N. and W., and scarcely ever S. and E. Stations sending returns of Thrushes are N. Unst, Pentland Skerries, Dunnet Head, Bell Rock, and I. of May. At the dates of the rushes they were accompanied by many other species. The rush at I. of May on 4th and 5th continued in great force after the wind shifted to S.E., with rain, after wind S. at noon, on 4th ("perfect weather for witnessing migration"), so fewer Fieldfares again on 5th, with wind—a W. gale, instancing the abruptness with which migration ceased owing to changes in the wind. A vast rush of Blackbirds, females predominating, on 12th, at I. of May, with S. haze and drizzle, but ceased utterly with change of wind to W. at 9 p.m. All birds striking on S.E. side, with the wind. Along with this rush came large numbers of Redwings and Fieldfares, Hooded Crows, one Yellow Bunting, large number of Larks, Robins, Bramblings, Chaffinches, eight Hedgesparrows, a few House Sparrows, two Woodcocks (shot). On the 15th Blackbirds as numerous as ever, but fewer Redwings and Fieldfares; hundreds of Snow Buntings, flying N. By the 17th Blackbirds were mostly males, but females had predominated up to that date. In January, 1885, between 4th and 21st, a few light records of Fieldfares and Thrushes, and a large number (rush?) on latter date. The rush on Nov. 4th consisted of Siskins and other Fringillidæ (these continuing in small numbers to the 6th, notwithstanding the change of wind). Mr. Agnew describes this as the largest rush of migrants this season at the I. of May, and it must have been very vast, close, and determined, when even on the 6th, with light W. wind, large numbers of Bramblings and Chaffinches still appeared. Other species participating besides the above were Siskins, Woodcocks (six killed), Rock Pipits, one Owl, two Falcons. (See notes upon weather under "Notes under Stations." We refer back to this account under other species, to dates).
Saxicolinæ.—Wheatears in considerable numbers at Pentland Skerries and Isle of May (a rush). Earliest at Isle of May March 26th, light S., two; and a few more on 28th at same station, including two old males. Rush with S.E. to S.W. wind at Pentland Skerries, on April 6th, and considerable numbers at I. of May on April 3rd. Beyond these there are no other spring records of this species. On March 31st a single Black Redstart (in mus. Feilden & Harvie Brown) is recorded from Pentland Skerries; light S.E., haze.[10] We have also three single records of the true Stonechat at I. of May, on 2nd, 28th and 30th April, and one at Pentland Skerries on May 14th, light E. wind, struck lantern, not killed. On April 30th a rush of Redstarts along with Robins, Ring Ouzels, &c., at Isle of May. This concludes spring records.
[10] A full record of this rarity, and of previous occurrences in Scotland, is given by me in Proc. Ryl. Phyl. Soc. Edin., read 23rd April, 1884; and a system of Record Forms recommended for tabular and formal records of rarities in future (see also Report for 1883, p. 81). We wish observers would recognise the use of some such uniform method, and we are certain it would save much time and trouble for future compilers.
In autumn records from N. Unst, one Redstart (the only one seen this year) and one Wheatear, on 7th and 12th September respectively; flew S.W. This is the earliest 1884 record of Saxicolinæ in autumn. Also from N. Ronaldshay, a number on 15th striking, and Pentland Skerries, Bell Rock, and I. of May, of Wheatears, a few Redstarts, Whinchats, &c., and one Black Redstart, old male, shot (in mus. I. of May, present curator Mr. Joseph Agnew). Another was seen the following day—first on 24th, second on 25th Oct. (recorded in full in Ryl. Phyl. Soc. Proc. 1885, read 21st Jan., 1885); a Common Redstart seen at same time.[11] The records of all the species are light, and no rush, unless of Wheatears, ut sup., Oct. 22nd, at Isle of May, increasing by the 25th. During our stay on the island (27th Sept. to 17th Oct.) we observed a good many straggling birds. A few accompanied the rush of other species on Nov. 12th (see Turdidæ). One Whitethroat is returned from I. of May, striking face of lantern, "facing the wind," on Sept. 12th. Mr. Agnew has the note,—to date of the 19th of September,—"I am surprised at so few birds with such thick fog." Log, light to strong E., thick fog, or haze between the 12th and 19th, yet migration was tardy.
[11] All the previous records of this species in Scotland relate to localities the position of which shows comparatively easily how they arrived at each. These records now amount to six in all, of which I have recorded the last three since Mr. Gray wrote his 'Birds of the West of Scotland.' They are as follows:—
